ST. PAUL, Minn. (WCCO) — Most of the community water systems in Minnesota are meeting federal guidelines for quality and safety. In a news release, the Minnesota Department of Health called the state’s 961 community water supply systems “generally safe.”

The annual report is based on routine testing for bacteria, nitrates, radiological elements and up to 118 different industrial chemicals and pesticides.

“You can be assured that the water coming out of your tap is more thoroughly tested and closely regulated than water from any other source, and that includes bottled water,” said Stu Thornley of the MDH’s water quality program.

Only one water system, which was not identified, exceeded government standards for pesticides and industrial contaminants. The MDH said the problem was fixed and the affected residents were notified.

Other problems, like the arsenic levels in 15 water systems, require more long term monitoring. More often than not, water systems outside the Twin Cities were noted for having problems.

“We’re fortunate that not only do we have good water quality but good water quantity in most parts of the state,” said Thornley.
